This 500-year-old cloister in the convent of Saint Augustine in Barcelona's old quarter is attached to a late 19th-century building that was a royal estate and later a fabric store for the past two decades. Following a stunning transformation by interior designers Elina Vila and Agnes Blanch of MINIM Studio the combined spaces now serve as an apartment for a young couple with a small child. All told, it's nearly 2,000-plus square feet of interior space plus the courtyard, which also includes a small gazebo by great Barcelona modernist Antoni Gaudi. Retained features include a Moorish-type solid wood door carved all in one piece. The cloister's outer wall was left unpainted to retain the antique look.
